Recognize and extract text from images or PDF documents. Supports multiple image formats and PDF files, automatically detects whether text is present, and preserves the original format in structured output. v2.1 uses a zero-additional-dependency approach: scanned PDFs are automatically rendered as images for AI visual recognition (no tesseract/rapidocr required); tables are structurally extracted using pymupdf’s built-in find_tables (no pdfplumber required); directories can be batch processed (PDFs and images extracted in one pass). Use when users need to extract text from images or PDFs, perform OCR, process documents containing text, extract PDF tables, batch process folders, or convert content to editable text. This skill’s capabilities come from RedFoxHub. Official site: https://redfox.hk/skills.

Run the full end-to-end observability setup for a service after its telemetry is already flowing into SigNoz: sequence SLI/SLO capture, data exploration (RED/USE), focused dashboards, saved Explorer views, burn-rate and absent-data alerts, and a tuning loop into one opinionated, SLO-aware workflow. Make sure to use this skill whenever the user says "set up observability after ingestion", "now that data is flowing, give me dashboards and alerts", "onboard this service to SigNoz end-to-end", "I want the full monitoring setup for X", or asks to go from raw telemetry to a complete dashboard + alerts + views package, even if they don't say "observability" explicitly. This is the orchestration layer: for a single artifact (just a dashboard, just one alert, just a saved view, or one static threshold alert, or a one-off query) use signoz-creating-dashboards, signoz-creating-alerts, signoz-managing-views, or signoz-generating-queries directly.

New to MCP?
From what the protocol is to installing your first server, these answers cover most first questions.
An open protocol that defines how AI applications connect to external tools and data in a uniform way. Clients talk to the model; MCP servers provide tools, resources and prompt templates. They exchange standard messages, so one server can be reused by many clients.
